y pecication forming part of Letters Patent No. 105,7@ 3, dated July 26, -i870.

To all whom 'it may concern.: *t i Be it known that I, HERMAN MILLER, of the city, county, and 'State of New York, have invented a new and Improved Tap-Nozzle for O ans and other Vessels,of which the follow ing is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of. this specification, and in whichl Figure 1 represents an `outside face view of `my invention-as applied to a can; Fig. 2, a

sectional view ofthe same, taken at right angles to Fig. 1; and Fig. 3, an'inside face view.

.Similar letters of reference indicate corresponding parts.

Although applicable to barrels and various vessels, it will sufce here to describe the invention as applied to cans, such, for instance, as those used for holding petroleum.

The object of the invention is to provide a cheapy nozzle that shall possess the characteristic of "a tap, and is secure against leakage, yet easily opened and closed, and provides for the discharge of the ent-ire contents ofthe can; also, that admits of the can being refilled, said nozzle not beingdestroyed or impaired in opening, and, by a suitable location of the can, an-

.swering as affaucet to draw upon or from;

likewise protecting the main body ot' the uid in the can from exposure to light when pouring from the can.

The in ven tion embraces, amon g others, three leading elements or features, namely, Va valve, a nozzle, and an interposed chamber between the valve and the nozzle, with the stem of the valve arranged to project through the chamber to the exterior, and with the nozzle made to occupy ra lateral position relatively to the valve and its stem orinterposed chamber.

Referring to the accompanying drawing, A represents the can,'in the one side or end of which is an opening covered by an outwardly protruding curved` plate, w, having an aperture, b, through it. Mounted on or over said plate is a chamber, B, which may be of a dome or other suitable shape, and which has attached to or provided on it, in lateral relation to the aperture b, a spout or bib, C, constituting the nozzle proper. D is a valve, here shown as arranged to close the aperture b from the inside of the can, by be- Y valve.

ing made ytol bear againstthe-inside face-of the plate1 a, but which may be arranged to close in a reverse direction. Projecting from the valve D, through the aperture b and chamber B, is a stem, E, having a screw-thread cut upon it, on which is fitted a nut, F, arranged to lie on the outside of the chamber B, and taking, its bearing on the exterior thereof, while a spring, G, is coiled around said stem on the interior ofthe chamber, B, said spring serving to open the valve vwhen the nut F is turned to admit of the same, a reverse action or turning of said nut operating to close the To prevent the turning of the valve and its screw-rod or stem, the valve may be steadied and guided by a flat or angular inside stem, H, arranged to work through a correspondingly-shaped slot in an interior bridge, I.

In some cases a bridge, with spout attached, may be substituted for the chamber B; but it is preferred to construct it in the form of a close chamber, as in such shape it not only serves as a bearing for the nut F, and for the one end of the spring G lying between it and the valve, and to carry the nozzle or spout, but constitutes a receiving-space for the oil or duid from the can in its way to the spout; and, by making' the aperture b of lesser area than the nozzle C, all bubbling at the nozzle when pouring is avoided, the oil or duid being quieted before reaching the spot by its entry within the chamber B. p

Exposure of the contents of the can to accident by light is also prevented by the interposed chamber B, the contents only of which are exposed, their being, in reality, two pourings from the canthat is, a first pouring into the chamber B, and a second pouring through the nozzle C. A vent-hole, o, should be made' in the chamber B to facilitate pouring from the bib.

It is preferred to make the nut F dish-shaped, to facilitate the sealing of the tap-nozzleafter the valve has been closed, and to construct the valve D so as to receive within its face, that closes against the plate a, an extended cork facing, s, arranged to project beyond the outside ledge that confines it, but only to a limited degree, whereby it is protected from injury by the contents of the can.

The curvature, as here shown, of the plate a, secures the flow of the entire contents of lthe can th rough the aperture I), while the bib C affords every facility for directing the disY charge, which Iii-.ty either he by inversion of the can, or by suitably locating it, as on a shelf, dnd drawing from the tap-nozzle as from a faucet.

What is here claimed, and desired to be secured by Letters Patent, is-

1. The combination, substantially as de scribed, of the hib C, the valve D, the interposed ychamber B, and the operating-stem E,

arranged to project through said chamber.

2. The combination of the inside guide or stem H of the valve D with the bridge 1', the chamber B, outer valve-stem or screw-rod E,

the spring G, and the nut F, substantially as 4 specified.

3. The outwardly-projecting curved plate or vnlve-seait al at the back 0r base of the chamber B, in combination with the bib G, of larger area than the dischztrgeeperture b thrcu gh said plate, essentially as herein set forth.

4.. The arrangement relatively to each other of the bib G, the cham ber B, the valve D, the

cperatingetem E, the nut F, spring G, the

guide H, and the interior bridge I, substantially as shown and described.
